Completed Servo Chron Bay
I finally got my ServoChron to work. The first time I programmed it two weeks ago, I didn't know exactly how I did it so it could be done agian. Last night I accidentally deleted it from memory but got it working against just like before. I have placed my board, servo, altimeter, batteries which I know I kind of heavy right now, and I will soon try to put a camera in there. Here is my demonstration. Tell me what you think. This is for the axial deployment system.

Re: Completed Servo Chron Bay
I got it rigged to my parachute now so I'm hoping today I can get a launch in with a 1.5 liter bottle rocket and a 2 second delay. Does that delay sound good?

Re: Completed Servo Chron Bay
Great! can't wait to see it in action. how much pressure are you going to launch with? At 60psi, ballistic flights don't last more than 3 sec.

Re: Completed Servo Chron Bay
So is a 2 second delay good or 1 second.

Re: Completed Servo Chron Bay
I was thinking like 100 psi. My launcher clamp broke but I can still launch until fixed by tossing a small brick at the launcher base which causes it to launch.

Just a suggestion- get your launcher fixed!

Re: Completed Servo Chron Bay
With the heavy batteries and payload, it might go higher than you think. I would urge him to run it through a simulator to figure out the correct timing. An early deploy can be as bad as no deploy at all.bugwubber wrote:Great! can't wait to see it in action. how much pressure are you going to launch with?

Re: Completed Servo Chron Bay
I'll run it through the Clifford health sim.

Re: Completed Servo Chron Bay
the are the results,
Coast
Drag-free coast 274.0 metres to apogee at 274.5 metres after 7.5 seconds
Actual apogee at 68.03 metres (223.2 feet) after 3.08 seconds
So I'll set the delay for 2 seconds because I don't think it calculates the time the parachute takes to unwind.

Re: Completed Servo Chron Bay
the split collar will take about 3 days to dry with the PL so it won't be fixed today. I may not launch today, because the launch to needs a replacement elbow that I don't have lying around. Besides it's a bit windy here.

What are you gluing on the split collar?Water Rocket Expert wrote:the split collar will take about 3 days to dry with the PL so it won't be fixed today. I may not launch today, because the launch to needs a replacement elbow that I don't have lying around. Besides it's a bit windy here.
All Purpose (PVC, CPVC, ABS) Cement is what I use on pipe.
I finally made my first gardena launcher. Used wire and JBWeld Putty to attach PVC pull down rings. Set and ready to go in 1 day.

Re: Completed Servo Chron Bay
I am using PVC glue for gluing the PVC, but I now am gluing the PVC couplings sides to the metal vice, which does not adhere to PVC using PVC glue. So I am using PL Premium. It dries a bit faster when it is not in an air tight environment like a splice. They fell off from me throwing bricks at it.b

Re: Completed Servo Chron Bay
What kind of JB Weld Putty did you use. Steel Stick, plastic weld, water weld?

Re: Completed Servo Chron Bay
I have both but Steel Stick for this since I used it to cover up the wire. Also added some filets of putty under the pvc rings to hold them in place really well.Water Rocket Expert wrote:What kind of JB Weld Putty did you use. Steel Stick, plastic weld, water weld?

Re: Completed Servo Chron Bay
2 sec sounds good. I was just looking over my 2 liter/100psi altimeter chart, it hit right at 2sec to apogee.Water Rocket Expert wrote:the are the results,
